Abstract
The invention discloses a cuttage propagation method for Juniperus horizontalis 'Golden Carpet' and belongs to the technical field of plant propagation. The method is characterized by comprising the following steps of: 1) uniformly mixing peat, pulverized reed leaves, yellow soil and an organic fertilizer in a volume ratio of (3-5):(3-5):(0.5-1.5):(0.5-1.5) which are taken as matrixes, and filling into a seedbed; 2) picking autumn tips obtained in the current year from female parents and cutting spikes, wherein the appropriate cuttage time is early November; 3) impregnating ear bases of cuttage branches for 2 to 3 seconds by using a Sensheng No.5 plant root promoter at the concentration of between 180 and 220ppm; 4) performing cuttage by using the seedbed, and entering a management and maintenance stage; and 5) performing seedling hardening when the rooting rate reaches about 95 percent. By the cuttage propagation method for the Juniperus horizontalis 'Golden Carpet', the rooting condition is good, and the yield reaches over 95 percent; and the method is high in propagation speed, can adapt to climate and soil environments in China, and has good market prospect, and propagation operation steps are simple.
Description
Technical field
The invention belongs to the plant propagation technical field, be particularly related to the hackmatack cuttage breeding method.
Background technology
Hackmatack
Juniperus horizontalis' juniper belongs to for Golden Carpet ', Cupressaceae, evergreen coniferous tree, and the floor file shrub crawls to expand to peripheral carpet type, and short, the bark taupe scales off; Height of tree 15cm-30cm drapes over one's shoulders needle, and tip is like needle point, and is green, golden yellow in the season of growth, is with aubergine winter; Cone berry shape, shape is little, circle.
Hackmatack happiness light, growing way is healthy and strong, and resistance is stronger; Organic soil or sandy soil are rich in happiness, and be drought-enduring, and the happiness draining is good, subacidity, neutrality and alkalescence soil, salt tolerant alkali.Hackmatack be mainly used in by being planted, plant in the slope, embankment protects, and also can adorn edge or rock plant; Can plant at coastal area, prevent erosion; Can be potted plant, do espalier, topiary; Can be planted in riverbank, slope etc. and locate to do protection usefulness.
It is northern that hackmatack originates in Europe, and its ornamental value is high, and wide accommodation all can be planted in China northeast, North China, southwest and subtropical zone; Abroad planted or basin is planted is well to view and admire green plants more with being used for, but still brand-new kind at home, market prospects are wide.Through inquiry to data of literatures, present domestic relevant scientific paper and the patent of hackmatack cottage propagation technology of still not having, this field still belongs to blank.
Summary of the invention
To the problems referred to above that exist in the prior art, the objective of the invention is to design the technical scheme that a kind of hackmatack cuttage breeding method is provided, it is simple to operate, reproduction speed is fast, and yield rate is filled up the blank of domestic correlative technology field up to 95%.
Described hackmatack cuttage breeding method is characterized in that may further comprise the steps:
1) choose suitable breeding spot and set up the maternal district of hackmatack cutting orchard, the cutting orchard seeding row spacing of planting is 40cm * 40cm, and density is 2400-2600 strain/mu, adopts the mode in seedbed, ground to set up the cottage propagation district simultaneously; With volume ratio is the peat of 3-5:3-5:0.5-1.5:0.5-1.5: reed jasmine: yellow soil: fertilizer mixes the companion as matrix and is packed in the seedbed after evenly, keeps the matrix elasticity consistent, and stromal thickness is 7-9cm, and to the matrix disinfection;
2) suitable cutting time is early November, and cuttage in 1 year 1 time takes the autumn then to cut fringe slightly from female parent, and fringe bar length does, 5.5-6.5cm wipes out the needle of fringe bar bottom 1.5-2.5cm, and leaf site 3.5-4.5cm is stayed on top;
3) the cuttage branch adopts No. 5 plants of gloomy life to urge root agent 180-220ppm dipping fringe bar base portion 2-3 second, and it is the methyl of weight ratio 4-6:1-3:2-4: GA that No. 5 plants of described gloomy life are urged the root agent
